Canada Weighs Lunar Microreactors
Canada is exploring the development of nuclear power systems for future moon missions through a new Request for Information issued by the Canadian Space Agency.
The agency states that Canada is not assuming a single domestic entity will design and deliver an entire end-to-end lunar microreactor system.
The planning envelope outlines a reactor capable of generating 20 kWe to 80 kWe of net continuous output. It requires an operational lifetime of at least 10 years, mostly autonomous capabilities, and safe deployment and decommissioning mechanisms.
Supply Chain Areas of Interest
The agency identifies 16 distinct areas of interest spanning the lunar microreactor supply chain. These categories include nuclear fuel, heat transport, power conversion, radiation shielding, deployment, and autonomous instrumentation.
Additional focus areas involve launch integration and workforce development. The Canadian Space Agency asks submissions to justify specific technologies or architectures for these components.
The agency outlines a potential pathway moving from initial feasibility studies to ground demonstrations and eventual flight tests. This structure helps identify where domestic organizations can contribute through local and international partnerships.
Radioisotope Technology Funding
The Canadian Space Agency recently funded two distinct projects focused on radioisotope technologies. Meanwhile, the Nuclear Innovation Institute launched the Canadian Centre for Space Isotopes to drive research and collaboration.
One funded project develops a tritium-fueled radioisotope heating unit designed to help spacecraft survive lunar nights. The second project creates a radioisotope power system to support rovers in harsh environments, keeping the proposed lunar utility vehicle in mind.
The new center convenes specialists from the nuclear sector, space industry, and broader research community. They aim to foster policy development and industry collaboration.
International Space Nuclear Push
Lunar surface power attracts growing international interest as space agencies plan long-term surface habitation. NASA established a lunar base as a key focus area and sought proposals for radioisotope power systems focusing on Stirling generators.
For the United States, this effort forms part of a broader push for space nuclear power. That larger initiative includes developing nuclear propulsion for the Space Reactor-1 Freedom mission, which is scheduled to launch in 2028.
